PHYSICAL EXERCISING APPARATUS.

Application filed. January 3, 1924.. Serial No. 684,243.

To aZZ whom it may concern.

Be it known that I, GUY CAMPBELL, a sub ject of the King of GreatBritain, residing at 24 Ovington Gardens, London, S. W. 3, England, haveinvented certain new and useful Improvements in or Relating to PhysicalExercising Apparatus, of which the following is a specification.

This invention refers to improvements in or relating to physicalexercising apparatus, and has for its primary object to provide a simpleand effective device of light, compact, and portable nature, by means ofwhich the muscles and tendons of the fingers, hands, wrists and forearmscan be exercised and the gripping power increased in a simple andeffective manner, thus rendering the device particularly applicable forthe use of sportsmen playing such games as golf, tennis, and the likewhere success at the game especially depends upon the strength of thefingers,

hands, wrists and forearms.

According to the present invention I provide physical exercisingapparatus for de veloping the muscles and tendons of the fingers, hands,wrists and forearms comprising a hand grip of elongated, cylindrical,torpedo, zeppelin, or other convenient form and dimensions to suit thesize of the users hands and constructed of india-rubber or likeyieldable and resilient materialadapted to offer a gradual resistance tothe pressure of the fingers and hand when the same is gripped.

In order that the present invention may be clearly understood and morereadily carried into effect it is hereinafter described with referenceto the accompanying drawings, in whichr Figure 1 is a full sized sideview of a hand grip constructed in accordance with the presentinvention, and V Figure 2 is an end view thereof.

As shown and according to the present invention I provide a resilienthand grip a preferably of elongated, cylindrical, torpedo, zeppelin, orother convenient form with rounded or flat ends and which is constructedof india-rubber or like resilient material which may if not solid, befilled with air or with other yieldable and resilient material. Thedevice may be made in one or more sizes to suit the size of the usershands, and is adapted to be held; in the hand at the base of the fingersand to be gripped and released continuously, thus offering a gradualresistance to the pressure of the fingers as the same is compressed andreleased, thereby developing the muscles and tendons and increasing thestrength and gripping power of the fingers and hands more effectivelythan by any other means.

The device is preferably of such a length asto project beyond the handof the user on each side, so that the air compressed therein at eachoperation will find its way into the extending end portions (1 thereof,thus ensuring at all times an even pressure conforming to the shape ofthe hand and the fingers. For the use of an average person the devicemay conveniently have an overall length of, say 5 inches and a maximumdiameter of say, about 1 inches, though these dimensions may be variedif desired.

In some cases the resiliency of the apparatus may be increased, oradditional resiliency may be obtained, by making the developer hollow,as by the provision of a longitudinally or diagonally arrangedperforation or perforations. In some cases also two of the gripdevelopers can be used or connected together if a stronger grip isdesired. For instance, two such grips could be used as separate membersarranged alongside of each other, or they could be moulded or otherwiseconnected together in pairs to form a single article.

What I claim is As an article of manufacture, a physical apparatus fordeveloping primarily the runs cles and tendons of the fingers, hands,wrists, and forearms, comprising a solid hand grip of a lengthcommensurate with the width of the hand and of elongated form andappropriate transverse dimensions, the grip being constructed ofyieldable and resilient sponge rubber, whereby to correspondingly resistclosing pressure of the fingers to promote muscular strain fordevelopment of the muscles.

In testimony whereof I have hereunto signed my name.

GUY CAMPBELL.
